The retrial phenomenon occurs inherently in a wide range of queueing systems.
The majority of retrial queueing models do not account for vacation.
However, in practice, retrial queueing systems undergo vacations for
maintenance or other reasons. In this study, we provide an in-depth analysis
of the many possible retrial queueing systems when Bernoulli vacations are
in effect. Moreover, this study outlines the key principles and reviews the
relevant literature. The framework of a retrial queue with Bernoulli
vacation has numerous applications in computer networking systems,
manufacturing and production mechanisms, inventory systems, including
network service, mail service and file transfer service, etc. Several
retrial queueing systems have been investigated, notably M/M/1, M/M/C,
M/G/1, M[X]/G/1, and Geo/G/1. Many other important situations, such as
server interruption, feedback, G-queue, impatient customers, priority
customers, etc., have been explored in relation to retrial queues with
Bernoulli vacation and the results of these investigations are also
highlighted. The foremost objective of this study is to help researchers,
administrators and technical workers who want to use queuing theory to
simulate congestion and need to know where to find details on the right
models. Finally, some open problems and potential future lines of survey are
also covered.
